Signal Description
Timer 0 Schmitt-Trigger Input/OutputÑ
When timer 0 functions as an external event
counter or in measurement mode, TIO0 is
used as input. When timer 0 functions in
watchdog, timer, or pulse modulation mode,
TIO0 is used as output.
This signal is driven by a weak keeper after
reset.
The default mode after reset is GPIO input.
This can be changed to output or configured
as a timer input/output through the timer 0
control/status register (TCSR0).
Timer 1 Schmitt-Trigger Input/OutputÑ
When Timer 1 functions as an external event
counter or in measurement mode, TIO1 is
used as input. When timer 1 functions in
watchdog, timer, or pulse modulation mode,
TIO1 is used as output.
This signal is driven by a weak keeper after
reset.
The default mode after reset is GPIO input.
This can be changed to output or configured
as a timer input/output through the timer 1
control/status register (TCSR1).
